BEAMFORMING IN MULTICAST COMMUNICATIONS - A simplified explanation of the abstract

This abstract first appeared for US patent application 20240298328 titled 'BEAMFORMING IN MULTICAST COMMUNICATIONS

Simplified Explanation

This patent application discusses methods, devices, and systems for beamforming in wireless communications, specifically focusing on multicast configurations. It describes how a transmitting device can send multicast data to multiple receiving devices simultaneously using a physical downlink shared channel (PDSCH) preceded by a physical downlink control channel (PDCCH). Receiving devices can determine the multicast data in the PDSCH based on information in the PDCCH and adjust their antennas to receive the data efficiently.

Original Abstract Submitted

this disclosure provides methods, devices and systems for beamforming in wireless communications. some implementations more specifically relate to beamforming configurations for multicast communications. a transmitting device may transmit multicast data to multiple receiving devices, concurrently, via a physical downlink shared channel (pdsch). the pdsch may be preceded by a physical downlink control channel (pdcch). the pdcch may provide scheduling information for the pdsch, including a multicast beam associated with the pdsch and a timing offset or delay between the pdcch and the pdsch. a receiving device may determine that the pdsch contains multicast data based on an indication in the pdcch. to receive the pdsch, each receiving device may tune its antennas in a direction of the scheduled multicast beam or a default beam based on the delay between the pdcch and the pdsch.
